LUCIAN R. CAKES, OF TIPTON, INDIANA, ASSIGNOR TO THE CAKES MANUFACTURING COMPANY, OF TIPTON, INDIANA, A CORPORATION OF INDIANA.

ELECTRIC HEATING COIL.

Application filed November 14, 1922. Serial No. 600,922.

7 '0 all whom it may concern Be it known that I, LUGIAN R. OAKES, a citizen of the United 'States, residing at Tipton, in the county of Tipton and State of Indiana, have invented certain new and useful Improvements in Electric Heating Coils, of which the following is a specification.

This invention relates to an electric heating coil and is designed primarily for use in heating incubators, brooders and similar devices, although it will be understoodthat it may be used for heating various other enclosures or for any desired purpose where a heating coil is required.

The prime feature of the invention is the provision of a coil proper which is preferably formed in one continuous section and doubled upon itself, the free ends of the coil being connected with any suitable electric circuit, and by constructing and arranging the parts of the coil in this manner it may be stored in a compact space and disposed in circular formation; if desired.

A further feature of the invention is the provision of a casing for enclosing said coil.

A further feature of the invention is the provision of means for supporting the coil within the casing.

And a further feature of the invention is the provision of means for mounting the coil and its casing in operative position.

Other objects and advantages will be hereinafter more fully set forth and described in the accompanying specification.

. i In the accompanying drawings,

Figure 1 is a detail elevation, partly in section, of an incubator showing the coil applied to use therein,

Figure 2 is a plan view ofthe coil and its casing with parts of the casing broken away, an

Figure 3 is a detail sectional view as seen on line 33, Figure 1.

As showing one manner of utilizing the heating coil, the coil 1 is shown as mounted within an incubator 2 which may be of any preferred construction, the coil 1 comprising an endless section which is preferably doubled upon itself, the two paralleling parts of the coils 3 and i being in this instance disposed in circular formation and having their free ends connected with circuit wires 5 and 6 respectively, the current passing through said wires 5 and 6 serving to energize the coil.

vals within the casing and attached to one section thereof in any suitable manner, preferably by tongues 10, which tongues are secured to one section of the casingand bent around the spools so as to hold them in position within the casing.

The casing 7 is suspended in any suitable manner, but preferably by means of hangers .11, said hangers having hooks 12 at their free ends which fit over and engage the beads at the edges of the casing 7 ,the bar portion of the hangers extending through clips .13 fitted to the face of the object in which the coil is mounted, in this instance the cover portion of the incubator 2. The hooked ends 12 of the arms of the hangers are held in engagement with the heads 8 by extending a cotter pin or the, like it transversely through the arms of the hangers, although other devices may be used for this purpose, if desired.

This form of heating coil may be very cheaply manufactured and readily applied to use, and while shown in the present instance as employed for heating the interior of an incubator, it will be understood that it can be used for any desired purpose where an electric heating coil is required.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a heaterhaving an electric heating element, a casing for enclosing said heating element, said casing comprising a pair of companion sections, one section having its edges crimped over the edges of the other section for securing said sections together, said crimped portions forming beads, means for mounting the heating element within the casing, hangers having means at their free ends for engagement with said beads, and means for clamping the hook portions of the; hangers in engagement with said beads.

2. In a heater having an electric heating element, insulating spools through which said heating element is extended, a-hollow casing enclosing said spools and heating element on the casing for anchoring said insulatin spools therewithin, and hangers for suspen ing said casing from the heater, substantially as set forth.

3. In a heater having an electric heatin element, a circular casing enclosing sai heating element, said casin being formed in companionsections an edges crimped together and forming beads, hangers for suspending said casing, hooks on said hangers for engagement with said beads, and means for locking the hangers in.

engagement with said casing.

4. In an electric heater having an electric heating element,-a casing for the heating element,.means for suspending the heating element within the casing, and means for suspending the casing from the heater, sub

v stantially as set fort having their tric heating element, a circular hollow, casing, means for suspending the heating element'at intervals within the casing, and

means for supporting the casing from the heater at intervals around the periphery of the casing, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at Kansas City, Missouri, this 26th day of Qctober, A. D. nineteen hundred and twenty-two.
